Description |
(1). A massive straight bar runs through this galaxy and contains the nucleus at the centre. It consists mostly of older stars that give a reddish color to the bar. (2). The gravitational perturbation from the galactic bar causes interstellar gas and dust clouds to form a pair of spiral arms that extend from the ends of the bar. Young luminous hot stats, born out of the interstellar clouds, give these arms a prominent appearance and a blue color. (3). The bar and spiral pattern rotates clockwise, one full turn takes about 350 million years. (4). The bright yellow nucleus likely houses a massive black hole.
(5).Astronomers believe the gravity field of NGC 1365's bar plays a crucial
role in the galaxy's evolution, funneling gas and dust into the central
star-forming maelstrom and ultimately feeding material into its massive
black hole. ¡@ |
